Good *** there's a lot of ******** on this forum. It was a very simple question. I don't need your high and mighty opionion of what I should be doing with my truck. Unlike some of you guys I have more important things to do than work on an old truck I rarely drive in the rain. You people have no...

Thanks for the suggestions guys, but this simply is not going to get fixed until at least late spring. I am not in Texas right now and it's about 40 degrees and raining. I've already replaced most of the ignition system, there's most likely a problem with the intake valve not closing for...

I have a carbed 7.4L engine in my Blazer. There is something wrong with one of the cylinders, not sure exactly what, but when it's spark plug wire is hooked up it backfires through the carb. When that cylinder's wire is unhooked, it runs fine. Is it bad to drive around like this? (on only 7...

I guess that's possible, but I've never heard of it happening before. Water wouldn't be any more likely to cause that than any other chemical though.

Water. It will work just as well, if not better than, anything you can buy in a can for six bucks. Spray a mist into your intake while the engine is at a fast idle. Be careful not to put in too much or you can hydrolock the engine, but that's nearly impossible if you just spray a mist into the...

This is somewhat related to the question I asked here a few days ago. What if you used a small percentage of biodiesel or new vegetable oil? That stuff is only around 3 bucks/gallon and even small percentages supposedly help diesels out a great deal. What kind of effect would that have on a cat...

Yes, that's exactly what I plan on doing.

Tom, why do you have such a beef with me using vegetable oil? Why do you keep suggesting I run random BAD things in my engine? Haven't you read any posts on this thread? The purpose is to use an oil that will have a POSITIVE effect on the engine. Gear oil or any of the other oils you suggested...

Just got back from Costco, they have Soybean oil for about $3.40/gallon. Canola was about $5.60/gallon. Would canola work any better than soybean oil?

I have a perfect test engine for this, a mid 70s 454 that has been quite neglected. I have to take the valve cover off anyway, so I'll try and take some before and after pics. I think I'll do the flush with fresh clean motor oil too just to see how black it gets. I think I have too much free...

What kind do you suggest I use? Unfortuneately, nearly $25/bottle isn't going to happen for the 15 vehicles I have to take care of. New veggie oil is only about $3-5/gallon. It would be easy to make a 5 gallon batch of biodiesel to keep around just for this use. I think I'm going to make a...

Why don't I mix gasoline with diesel? Because it would provide me no benefits and ruin whatever kind of engine you put it in. Mixing 20% vegetable oil into diesel fuel on the other hand lowers emissions, increases lubrication, decreases emissions, and cleans out your fuel system VERY well. This...

Again, talking about NEW vegetable oil. Biodiesel is any fuel made from plant oils, whether it's new or used oil. If you added 1 quart to a 5 quart crankcase that would be like B20. (20% biodiesel/80% petrolium diesel) I know there are thousands of people that run this in completely unmodified...

I was thinking more like a temporary flush, you know, add a quart, let the engine idle for a little while or take it for a short drive, and then dump the oil. What if you used regular biodiesel and not just vegetable oil? I'm not completely sure about what goes into the making of it yet, but I...

Given some of the ridiculous fuel prices lately I've been looking into biodiesel, though I don't have a diesel vehicle yet. What I've learned is that vegetable oil as compared to diesel is a very strong solvent and adds lubrication. What if you added around a quart of fresh new vegetable oil to...
